Over at the South by Southwest Film and Musical Festival in Austin, Texas, plenty of new movies and tunes are debuting, but one classic trend is holding steady: black and white fashion. Olivia Wilde (in Dolce & Gabbana), Ashley Benson, and Genesis Rodriguez, all on-hand to premiere their latest films, worked the tones in tandem, and they made each lady look cool and confident. It's a reassuring palette—especially when organized in crisp grids or lines, like Wilde's Dolce number. But if you try the trend yourself and want to lessen the impact, add another color, like Rose Byrne, who paired her pinstriped A-line skirt and white accessories with a peach Balenciaga button-down blouse. (Tip: You can also add color with a bright pump or bold lips.) But remember, you don't need much makeup—just filled brows and contoured cheeks; let your sharp outfit take center stage.
